dlocate and grep-dctrl for example. interestingly, 'apt-cache show' is even faster than dlocate (which makes use of grep-dctrl to do the search). $ time apt-cache show dpkg >/dev/null real 0m0.235s user 0m0.210s sys 0m0.030s $ time dlocate -s dpkg>/dev/null real 0m0.407s user 0m0.380s sys 0m0.010s $ time dpkg -s dpkg>/dev/null real 0m1.517s user 0m1.410s sys 0m0.100s craig -- craig sanders
